Abstract: the paper presents the rationale for the use of spectral decomposition apparatus for the development of a mathematical model of the electromechanical system of a drum-type winch with an asynchronous motor as a drive. The technique of obtaining a mathematical model of the winch with electric drive on the basis of pulse transient response is described. The requirements for the mathematical model of the winch and the results of mathematical modeling are presented. The results of mathematical modeling show a proportional change in power consumption, the effort in the polispast, electromagnetic torque, rotor speed, depending on the time and stage of lifting. The results of full-scale tests of the drum-type winch under conditions similar to mathematical modeling show that the mathematical model is adequate. On the basis of the simulation results, it is proposed to use the new method of finding the value of the loading mode coefficient to determine the operating mode of the drum-type winch.
